ARTHUR F. SMARDON, OF MAYWOOD, ILLINOIS.

OIL-BURNER.

Specification of Letters Patent.

Application filed February 24, 1911.

Patented Oct. 3, 1911. Serial No. 610,499.

To all whom it may/concern:

Be it known that I, ARTHUR F. SMARDON, a citizen of the United States, residing at Maywood, county of Cook, and State of Illinois, have invented certain new and use` ful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to improvements in oil vaporizing burners of that class in which oil-gas is generated and mixed with a certain amount or percentage of air and adapted to burn a low grade of refined oil, or any ordinary petroleum-oil generating an oilgas which will burn with an intense heat and a clear flame. The burner is of the class adapted to be placed in the lire-box or i combustion chamber of any type of stove@ range, furnace, boiler, or wherever wood or 1 coal is used for heating and cooking purposes.

The object of the invention is to provide an oil-burner which meets all the requirement-s for liberating gas from oil by bringing t-h-e oil into a receptacle and presenting a large surface for evaporation. V

A further object is to so design the burner that the heating flame produced thereby will heat uniformly and at any temperature desired.

A further obj-ect of the invention is to provide an oil-burner of the class stated which shall be economical to manufacture and efficient in operation.

Other objects will appear hereinafter.

ith these objects in view my invention consists in the novel construction and arrangement o-f parts all as will be hereinafter fully described and more particularly pointed'out in the appended claims.

My invention will be mo-re readily understood by reference to the accompanying drawing forming a part of this specification, and in'which,

Figure l is a side elevation of an oilburner embodying my invention, Fig. 2 is a top plan view thereof, Fig. 3 is a top plan view of the burner, the hood or top thereof being removed, Fig. A is an end elevation, and Fig. 5 is a central vertical transverse section.

The preferred form of construction of my invention as illustrated in the accompanying drawing comprises an elongated rectangular base member l which is of a size to fit the lire-box of any ordinary cooking stove or range. Formed in the base member l is an endless oil vaporizing chamber 2 which is substantially U-shaped in cross section as illustrated in Fig. 5. The inner walls of the vaporizing chamber 2 surround an elongated rectangular air opening 3 through which air ascends to supply the draft of the flame as indicated in Fig. 5. The exterior walls of the chamber 2 are provided with a series of air perforations 4L through which air flows into the chamber 2 to facilitate in producing the gaseous combustible mixture. An oil supply pipe 5 is provided with a regulating cock (not shown) and extends upwardly into the air o-pening 3 as illustrated in the several views. The upper end of the pipe 5 is provided with a horizontal v T connection 6 the ends of which pass through apertures 7 provided in the interior walls of the chamber 2. Screwed to the ends of the T connection 6 is a pair of T ends 7 the openings or orifices of which are located vertically over a pair of shallow troughs 8 centrally located in the bottom of the chamber 2. From this construction and arrangement it is clear that when oil drips from the orifice of the T ends 7 that pools of fuel will be formed in the troughs 8. When these pools overflow the entire bottom of the chamber Q will be flooded with oil thus presenting a large vaporizing surface. During evaporation of the oil from the large vaporizing surface thus formed vapor will ascend as indicated by arrows in Fig. 5 and be directed to the flame opening 9 provided in the curved sheet -metal hood 10 which is superimposed and secured to the base l by means of a series of rivets ll. The hood l0 is co-extensive with the top of the chamber l and is provided with downwardly deflecting surfaces l2 in the top thereof due to the influence of which the rising vapor will be obstructed somewhat in its upward llow which causes a thorough mingling of the air with the fuel vapor. The sides of the walls of the flame opening 9 are vertically and parallelly disposed and the same are located directly over the main central air opening 3 as clearly illustrated in Fig. 5.

It will be observed that air is supplied to each side of the vapor which arises from the bottom of the chamber l, the opening 3 supplying air for one side of the vapor and the perforations A air for the other side. Consequently, when the combustible mixture thus formed reaches the flame opening 9 the fuel particles are thoroughly commingled with air which is necessary for the complete and perfect combustion of the fuel. The result is that an intense heat is produced by the flame without the presence of odor or smoke.

An oil-burner of the construction set forth is highly useful since it fulfils all the requirements of a burner of this class. And the simplicity of construction and efliciency of operation of the burner renders the same especially adapted for domestic use.

Thile I have illustrated and described the preferred construction for carrying my invention into effect this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise4 details of construction as set forth but desire to avail myself of such variations and modifications as fairly fall within the spirit and scope of the appended claims.

I-Iaving described my invention what I claim as new and desire to secure by Letters Patent is:

1. In an oil-burner, the combination of an oblong rectangular casing having longitudinal oil vaporizing chambers at either side and a central narrow longitudinal air open ing in the bottom thereof between said chambers; means for supplying oil to said chambers; and a hood for said casing having a narrow central longitudinal opening in the top thereof located above said air opening, substantially as described.

2. In an oil-burner, the combination of an oblong rectangular casing having longitudinal oil vaporizing chambers at either side and a central narrow longitudinal air opening in the bottom thereof between said chambers; a supply pipe passing into said opening; branches in said pipe leading into said chambers; and a hood for said casing having a narrow central longitudinal opening in the top thereof located above said air opening, substantially as described.

3. An oil-burner comprising a rectangular base member having an endless vaporizing chamber U-shaped in cross section formed therein, means for supplying air to said chamber comprising a central rectangular air opening formed in the bottom of said base member, an oil supply pipe connected to said chamber, and a superimposed hood secured to said chamber having a narrow flame opening arranged vertically over said air opening, substantially as described.

Il. In an oil-burner, a rectangular base member having an endless vaporizing chamber U-shaped in cross sectionl formed therein, there being an elongated central air opening in said base member, an oil supply pipe leading into said opening and thence branching through openings provided in the inside walls of said chamber to the interior thereof, the outside walls o-f said chamber having a series of air perforations formed therein,l and a curved metallic hood inclosing said chamber and having a narrow elongated flame opening located vertically over said elongated air opening, substantially as described.

5. In an oil-burner, the combination with a rectangular base member having an endless vapo-rizing chamber formed therein, of an oil supply pipe leading into said chamber, there being an elongated central air opening in said base member and the outside walls of said chamber having a series of air perforations formed therein, and a curved hood inclosing said chamber and having a narrow elongated flame opening located vertically over said elongated air opening and of a length substantially coextensive therewith, substantially as described.

)6. In an oil-burner, an elongated rect-angular base member having an elongated rectangular air opening and an endless vaporizing chamber formed therein, there being a pair of shallow troughs formed in said chamber and a series of air perforations provided in the exterior walls thereof, an oil supply pipe leading into said elongated air opening and having a T connection passing through the interior walls of said chamber, the discharge ends of said T connection being vertically over said troughs, and a hood over said chamber having an elongated flame opening arranged over said air opening, substantially as described. u

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
